GUARD FOR FERMENTlNG-VATS.

SPECIFICATION forming part of Letters `Patent No. 444,944, dated January20, 1891.

Application filed October 17, 1890. Serial No. 368,464. (No model!) To@ZZ whom t may concern.:

Be it known that I, GUSTAV SOBOTKA, of the city of New York, in thecounty of New York and State of New York, a citizen of Austria- Hungary, have invented certain new and useful Improvements in Guards forFermenting- Vats, of which theA following is a specification.

This invention relates to improvements in vats, tubs, or receptaclescontaining liquids of a foaming nature; and the object of my inventionis to provide a guard forsuch vessels, which guard can be raised orlowered, according as the foaming of the contents of the vesselincreases or decreases.

The invent-ion consists inthe combination, with a vat, of a series ofrings guided to move up or down on the top of the same and a ilexiblesleeve connecting said rings.

The invention also consists inthe construction and combination of partsand details, which will be fully described hereinafter, and finallypointed out in the claim.

In the accompanying drawings, Figure 1 is a vertical transversecross-sectional view showing the guard lowered, parts being broken out.Fig. 2 is a similar View showing the guard raised; and Fig 3, is asectional plan view on the line w Fig'. 2'.

Similar letters ot' reference indicate corresponding parts.

On the rim of the vat, tub, or vessel A a wooden ring B is secured, andfrom said ring four or more or less iron rods .I project upward, theirtop ends being fastened in the ceiling of the room in which the vesselis placed. Said rods pass through two rings D D', adapted to slide upand down on the said rods. The fixed ring B and the sliding rings D Dare connected by a sleeve G of fabric, ruber, cloth, or any otheranalogous exible 1naterial, the height of said sleeve of flexiblematerial being dependent on the height of the room. The cloth or fabricis fastened se 'curely to the inner sides of the rings and the edges aresewed tightly together. To the uppermost ring chains or cords E arefastened, vwhich pass over pulleys F, and are provided at their oppositeends with counter-weights G. As the foam in the tub or vessel rises, theuppermost ring1 D is raised to acertain height, it being held in placeby the counter-weights, and thus forms a cylindrical Aguard on the topof the vat or tub and prevents the over iiowing and loss of its foamingcontents. If the guard is not of sufcient height and the foam passesover the top, the upper ring D is raised still higher and theintermediate ring D raised correspondingly. The guard can easily be adjusted to any desired height, as circumstances may require, and thus doesaway with the necessity of using the expensive high tubs used heretoforeto prevent the overflowing of the foam in the vessel.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination, with a vat, of a series ofguide-rods projecting upward from the top of the same, rings of the samediameter as the top of the vat, through which rings the guiderods pass,so as to adapt said rings to slide on said guide-rods, a collapsiblesleeve open at the top and bottom and secured to said rings and to thetop of the vessel, and counterbalancing -weights connected with the topring for the purpose ot' forming a collapsible vessel open at the top,substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

GUSTAV SOBOTKA.
